Hi, quick question, if I connect the TMP102 V+ to the arduino onboard 3.3v, do I need to level shift the SDA & SLC signals, or can I connect them directly to Analog4/5 on the Arduino?
In the comments section of the product page (http://www.sparkfun.com/commerce/produc ... ts_id=9418
) You(?) have said:
"I have an Arduino duemilanove, and have the tmp102 working. I connected V+ to the 3.3v pin on the Arduino board. Ground and Add0 to ground. SCL to analog pin 5, and sda to analog pin 4. The Alt connection is not needed. Here is my code, to read the sensor and print it through the serial port. I hope it helps. "
I am also aiming to connect an RTC module (BOB-00099) on the same I2C bus, which is running ok at the moment. So not sure if it's all going to work.. (First time playing with I2C)...
